How much would I need in my network to carry cam's over my network.

I have a DVR security system with cam's attached to it .

All I have to do is connect an Ethernet cable to it and I can access it from anywhere on my network.

What bandwidth do I need.
I also need the ability for this bandwidth to be carried wifi because the DVR streams will be going partly over a wifi connection between two buildings refer to link above for layout

You should have no problem accessing the DVR via your network even if it is going across a wireless bridge. Most DVRs (at least all the ones I have used) will send the video using the UDP protocol which meaning the video output you see will adjust for the bandwidth available - the more bandwidth the higher the framerate.

I have a dvr setup at home that I can remotely view using a 2MB connection without issue. The image updates about every 0.2 secs but it is very watchable.

Depends on the number of cameras, resolution and frame rate.

Say one camera at 15 frames per sec of medium quality with resolution of CIF (352x288) would need about 250kb/sec
